| Abstract(in English) | The flight control of drones and the transfer of captured video data by using the mobile communication network will be expected. We are proposing a "three-dimensional spatial cell configuration" in which ground cells and sky cells share the same frequency at each base station by utilizing 5G beamforming technology. In order to evaluate the proposed method accurately, a radio wave propagation model that can be used in the sky cell is necessary. Since drones flying over the sky are generally outlook, propagation is based on Nakagami-Rice model, and it is necessary to model the K-factor. We proposed a highly accurate "3D spatial circular orbit measurement method" that takes into account the characteristics of the radio wave arrival angle in the sky. In this paper, we evaluate the measurement accuracy of the K factor measured in the actual field using the proposed method. |
